unable to emit vectorized code in LLVM IR
I want to vectorize the user given inputs. when opt does vectorization user
supplied inputs (from a text file) will be added using AVX vector
instructions.
as you pointed; When i changed my code to following:
int main(int argc, char** argv) {
int a[1000], b[1000], c[1000];
int aa=atoi(argv[1]), bb=atoi(argv[2]);
for (int i=0; i<1000; i++) {
a[i]=aa, b[i]=bb;
c[i]=a[i] + b[i];

Error in v64i32 type in x86 backend
Have you read http://llvm.org/docs/WritingAnLLVMBackend.html and
http://llvm.org/docs/CodeGenerator.html ?
http://llvm.org/docs/WritingAnLLVMBackend.html#instruction-selector
describes how to define a store instruction.
